^ FLANGING-HEAD FOR RECEPTACLES;

Specification of Letters Patent.

Patented Dec'. 28, 1909.

Application led January 29, 1909. Serial No. @75,005.

To all whom it may concern:

Be it known that I, LoUIs C. KRUMMEL, a citizen of the United States, residing at Clinton, in the county of Middlesex, State of Connecticut, have invented certain new and useful Improvements in F langing- Heads for Receptacles, of which the following is a description, reference being had to the accompanying drawing, and to the characters of reference marked thereon.

My invention relates to new and useful improvements in Hanging heads for receptacles, and more especially to Hangingheads adapted .to turn a Hange on the body of a can, preparatory' to placing a cover on said can.. a

An object of the invention is to provide a Hanging head which shall be simple in con- -struction and durable in operation.

A further, object of the invention is to provide a Hanging head, in which all ofthe essential parts required for turning a flange on a receptacle, are supported and operated by the Hanging head.

A further object of the invention is to provide a Hanging head which includes aA spindle carrying Hanging rollers, with forming slides which are supported by the head and are operated by means contained within said head. I

A further object of the invention is to provide apHanging head which may be readily adjusted to operate upon dii'erent sized cans or receptacles.

Still further objects of the invention will in part be obvious, and will in part be hereinafter more fully described i In the drawings which show by way of illustration one embodiment of the inventiem- Figure 1 "is a sectional view through the Hanging head, showing the parts in positionfor receiving the can body whichhas to be Hanged, the forming slides having moved part way toward their inner position; Fig. 2 'is a similar View, with the parts in the position for Hnishing the flange; Fig. is a side elevation of my Hanging head, and showing a portion of the supporting trame for the same; Fig. 4 is a detail view, showing the wrist plate for the Hanging rollers; Fig. 5 is a top plan view of the Hanging head', showing in dotted lines the levers for the end cap' plate removed and the forming slides iii-their inner position; also showing in dotted lines the limiting nuts for the' outer sleeve.

My improved'Hanging head comprises a supporting spindle 1, which carries an inner sleeve 2. The spindle l is threaded into the end of a shortvertical shaft 3, and by disconnecting the shaft 3 from the spindle l the entire head/ may be removed from the machine Without in any way disassembling the parts of the head.

The short vertical shaft 3 extends through the sleeve 2, and said sleeve is held on the short vertical shaft by means of a nut 4. The short vertical shaft 3 is enlarged at its upper end to receive the threaded portion of .the spindle, and intermediate the enlarged upper end of the shaft 3 and the sleeve 2 is' a ball bearing 5, which receives the end thrust when the head is lowered on to the 'can body to Hange the same. The sleeve 2 is bearing 5, as clearly shown in Figs. l and 2 of the drawing.

The short vertical shaft 3 carries at its lowerv end a wrist plate 6, into which is threaded studs 7, 7, supporting Hanging rollers 8, 8. The wrist plate 6, as shown in Fig. 4, is provided with a plurality of seats for the Han ing rollers, which seats are spaced at di erent distances from the center of the wrist plate. The purpose of this con- `struction of' wrist plate is to allow the shifting of the position of the Hangingrollers, so that said rollers may be properly located for operating upon different sized cans or rece tacles.

T e spindle 1, which supports the Hanging head may be mounted in any suitable suporting structure, and may be rotated either y hand' or automatically, although, of course, it is preferable to rotate' said spindle automatically. The spindle in the present illustration of my invention is reciprocated longitudinally in order to bring the Hanging head into contact with the` receptacle of the body to. be Hanged. Said reciprocation of the spindle may be caused automatically, or the dspindle may bev moved manually, if deslre The essential features of, the invention consist in the Hanging headgand'; as a means for operating the Hanging'jhead, of course it is necessary that the spindle supporting the same be given avrelative movement to the body of the receptacle being flanged, and also a longitudinal movement, in order to bring the Hanging rollers into operative contact with the body of the receptacle. As a matter of fact, my improved Hanging head may be used in any ordinary drill press, if desired.

Coperating with the Hanging rollers'are the forming slides 9, 9, 9, 9. Sald slides are .similar in construction and operation, and, therefore, a description of one of these slides will answer for all. The slide 9 moves back and forth in a recess 10 in the cap plate 11, which is screwed to the lower end of an outer sleeve 12, (see Fig. 3). Said outer sleeve 12 is provided with a central cylindrical recess to receive the inner sleeve 2. Limiting bolts 13, which may be of any desired number, are carried by said outer sleeve and extend through an opening in the outwardly eX- tending Hange 14 of the inner sleeve 2 (see Fig. 3). Said bolts 13 are each provided with a head or nut which engages the upper face of the flange 1'4. The outer sleeve 12 'is recessed about the bolts 14, as shown in dotted lines in Fig. 3, and a spring 1.5 surrounds each of the bolts 13, and is located in said recess. Said springs bear against the lower face of the flange 14. The purpose of the springs 15 is to keep the inner and outer sleevesin the position shown in Fig. 3; that is, with the inner sleeve movedout of the outer sleeve until the same contacts with the head of the limiting bolts. l

Each of the slides 9 is operated by a. lever 16, which is carried by a pivot bolt 17. The lower end of the lever 16 is provided with arounded ortion 18, which extends into an opening 1n the slide 9, and rests against a wear plate 19, located in said opening. TheL upper end of the lever 16 carries a roller 20. A spring 21 is carried in a recess in the lever 16, and engages at its outer end the inner face of the outer sleeve 12. Said springs operating in connection with the levers, tend to hold the forming slides in their extreme outer position.

The inner sleeve 2 is provided with a cam plate 22, which is secured to the inner sleeve by a suitable bolt 23. The lower end of the plate 22 is beveled .to form a cam surface 24.

-When the inner and outer sleeves are expanded, that is, separated to the 'extent shown in Fig. 3, the rollers 20 are at the lower ends of the cam faces 24 on the cam roller 2O would then pass up onto the outer face of the plate 22, and hold said forming slidesI Vat their extreme inner position.

As above noted, theentire Hanging head is supported and reciprocated by the spindle 1. As a means for causing a movement of the outer sleeve relative to the inner sleeve, I have shown herein, the outer sleeve provided with projecting portions 25, 25, (see v Figs. 3 and 5). vSaid projections 25 are provided withlopenings 26, through which pass bolts 27, which, as herein shown, are carried by the supporting,framework 28 of t-he machine. Circular nuts 29 are threaded on the bolts 27, and the outer sleeve is cut away, as shown at 30 in Fig. 6, so'that said outer sleeve may reciprocate freely up and down on the bolts 27.

The outer sleeve, as shown in Fig. 2, is notched to receive the cam plates 22, and

said cam plates will, therefore, prevent the inner sleeve or the outer sleeve from rotating relative to each other, and at the same time allow the' outer sleeve to reciprocate relative to the inner sleeve.

The bolts 27 passing through the projections on thev outer sleeve, will prevent the outer sleeve from rotating, although allowing said outer sleeve .to reciprocate until said projections 25 engage the limiting nuts 29 carried by said bolts 27.

The forming slides 9, as shown in Fig. 6, are curved at their inner ends, and are so proportioned that when said slides are in thelr innermost position, said slides meet, forming a continuous circular opening. The opening in the slides should, of course, be of substantially the same diameter as the outer diameter of the body of the receptacle on which it is desiredto turn a Hange, so that said forming slides will serve as an anvil onto which the vHange of thel can body may be turned by the forming rollers.

In the .operation of my device, the can bodies are placed underneath the Hanging head on any suitablesupport. The Hanging head, as herein shown and described., is lowered on to the can body indicated 'at B in Fig. 1; As soon as the projections 25 on the outer sleeve engage the limiting nuts 29, the downward movement of the outer sleeve and the forming slides will cease. A further downward .movement of the spindle 1 carries the inner sleeve down into the outer sleeve. The cam surfaces 24 engage the rollers on the operating levers, and move the forming slides inward against the can body. After theA forming slides have been brought into Contact with the can body, the rolls 20 will pass on to the parallel outersurface of the cam plates 22, and hold the forming slides against the can body. A further downward movement of the spindle 1 causes the Hanging rollers to contact with the upper edge of, the receptacle to be forming slides, as shown in Fig. 2.V Aftery the Hanging operation has been completed,

the` spindle 1` rises, carrying with it the in-v ner sleeve andthe springsv 15` will serve to `hold the outer sleeve" down in contactgwliththe limiting nuts 29 until after the rollers 20 have passed down .oif the cam surfaces, thus allowing .the springs 21 to withdraw the" slides f from i underneath the` flangeV v formin forme on thfbody ofthe receptacle, Thel Harige car-ried'by'the inner sleeve then ien-`A g'ages .the heads'tof'the bolts 13, andraises .the outer sleeve pif: fr o'ln'the nuts'29,ian`d.

The width of the Hange on the can body, may be readily varied by varying the position of the limiting nuts 29', and, of course, l varying the stroke of the spindle, so that the Hanging .rollers will be brought into proper coperative relation with the forming slides.

Supposing the can to rest on a stationary' table, it will readily be vseen that if the limiti ing nuts 29 are lowered, the outer sleeve Will move down farther on the .can body before it is brought to rest by Contact with the nuts 29, and, therefore, a greater portion of the can bodyv will extend above the* forming l slides. lf now the Hanging rollers are brought down on to the can body, all of the.
